Pericarditis
Pericarditis is a condition in which the sac-like covering around the heart (pericardium) becomes inflamed.
Causes
The cause of pericarditis is unknown or unproven in many cases. It mostly affects men ages 20 to 50 years.
Pericarditis is often the result of an infection such as:
- Viral infections that cause a chest cold or pneumonia
- Infections with bacteria (less common)
- Some fungal infections (rare)
The condition may be seen with diseases such as:
-
Cancer (including leukemia)

Exams and Tests
When listening to the heart with a stethoscope, the health care provider can hear a sound called a pericardial rub. The heart sounds may be muffled or distant. There may be other signs of excess fluid in the pericardium (pericardial effusion).

Treatment
The cause of pericarditis should be identified, if possible.
High doses of nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or indomethacin are often given with a medicine called colchicine. These medicines will decrease your pain and reduce the swelling or inflammation in the sac around your heart. You will be asked to take them for days to weeks or longer in some cases.
If the cause of pericarditis is an infection:
- Antibiotics will be used for bacterial infections
- Antifungal medicines will be used for fungal pericarditis
Other medicines that may be used are:
- Corticosteroids such as prednisone (in some people)
- "Water pills" (diuretics) to remove excess fluid
- Other anti-inflammatory agents
If the buildup of fluid makes the heart function poorly, treatment may include:
- Draining the fluid from the sac. This procedure, called pericardiocentesis, is done using a needle, which is guided by ultrasound (echocardiography) in most cases.
Pericardiocentesis
Pericardiocentesis is a procedure that uses a needle to remove fluid from the pericardial sac. This is the tissue that surrounds the heart.
Read Article Now Book Mark Article - Cutting a small hole (window) in the pericardium (subxiphoid pericardiotomy) to allow the infected fluid to drain into the abdominal cavity. This is done by a surgeon.
Surgery called pericardiectomy may be needed if the pericarditis is long-lasting, comes back after treatment, or causes scarring or tightening of the tissue around the heart. The operation involves cutting or removing part of the pericardium.
Outlook (Prognosis)
Pericarditis can range from mild illness that gets better on its own, to a life-threatening condition. Fluid buildup around the heart and poor heart function can complicate the disorder.
The outcome is good if pericarditis is treated right away. Most people recover in 2 weeks to 3 months. However, pericarditis may come back. This is called recurrent, or chronic, if symptoms or episodes continue.
Scarring and thickening of the sac-like covering and the heart muscle may occur when the problem is severe. This is called constrictive pericarditis. It can cause long-term problems similar to those of heart failure.
Constrictive pericarditis
Constrictive pericarditis is a process in which the sac-like covering of the heart (the pericardium) becomes thickened and scarred. Related conditio...

Contact your provider if you have symptoms of pericarditis. This disorder is not life threatening most of the time. However, it can be very dangerous if not treated.
Prevention
Many cases cannot be prevented.
